    CHAPTER 3: A BIT OF HISTORY In the beginning... Most early recording consoles had very primitive equalization capabilities, often consisting of only two knobs. These consisted of either a simple ‘tone control’ type shelving equalizer, or a ‘low’ and ‘hi’ control knob with a fi xed frequency center.
  • Page 9 ENGLISH WARRANTY NOW LET’S GET STARTED TECHNICAL SPECS What followed next was the innovation that brought the use of EQ into the A BIT OF HISTORY mainstream, known as active equalization. ‘Active equalization’ allowed an EQ WAXING PHILOSOPHICAL to be patched into a mixing desk for the fi rst time without the fear of ‘insertion HOOKUP DIAGRAMS loss’, added noise, or loss of fi...

TIPS ON USING YOUR EQP-WA The EQP-WA is a program equalizer by design, which means, though quite capable on individual instruments, it especially shines on complex, full bandwidth material; i.e. complete mixes or instrument groups. It is especially good with providing a fi...
  • Page 11 When in bypass mode, the audio signal is still routed through the Cinemag input transformer, dual vacuum tube stage line amplifi er, and Cinemag output transformer; and the EQP-WA will output at approximately unity gain relative to the input level (or within close margin, due to small variations in output gain from individual vacuum tubes).
